SEAT-PADDING MAC HINE.

Application filed June 16, 1923. Serial No. 645,891.

To all whom it may concern:-

Be it known that I, ALLISTER S. MITCHELL, a citizen of the United States, residing at Oakland; in the county of Alameda and My invention is an improved padding ma-' chine particularly applicable in placing the padding in the pockets of an automobile seat back, or similar article.

The object of my invention is to provide a padding machine which is simple in construction, and all the moving parts of which are manually controlled, thus enabling it to be stopped at any time and a defect corrected. p

In the annexed drawing, I have shown the preferred form of my invention, but it may also be'embodied in other forms, and in this application I desire to cover my invention in whatever form it may be embodied.

Referring to the drawings:

Figure 1 is a side view of my improved padding machine.

Figure 2 is a'plan view of the same.

F igure' 3 is a sectional view taken on the line 3-3 of Figure 1.

Figure 4 is .a sectional view taken on the line 4-4 of Figure 1.

Figure 5 is a side view of thedriving mechanism associated with the table.

Figure 6 is a side view of the cutting hives. v Referring more particularly to the drawing, upon a suitable bed 1 are mounted a plurahty of filling tubes 2. These tubes are all mounted upon a threaded shaft 3 which is journaled in a bracket 4 on the bed 1. Carriages 5 are clamped to the tubes 2 and the shaft 3 is threaded therethrough. Thus when the hand wheel 6 on said shaft is rotated the tubes will be moved transversely over the bed 1 and adjusted as desired.

Tracks 7 are mounted on the bed 1 and a I table 8 is adapted to travel on said tracks articles. "A plurality of holdin ta le.

u on wheels 9 which are journaled onthe The table is split lon itudinally and an adjusting screw 10 extends into the two halves thereof, thus permitting the table to be widened to accommodate various sizes of fingers 11 are secured to a shaft 12 which 1s journaled at the front end of the table 8, and a lurality of holding fingers 13 are secur to a shaft 14 which is journaled at the rear end of the table. Arms 15 and 16 are formed on each of the fingers 11 and 13 respectively, A plurality of cams 17 are 0 mounted upon a shaft 18 which is journaled from the table 8 and are adapted to engage the arms 15 to move the said arms and fingers 11 downwardly to engage the back which is being padded.

A plurality of cams 19 are mounted upon a shaft 20 which is journaled from the table 8, and are adapted to engage the arms 16 to depress the fin ers 13 which will thus engage the seat bac on the table. Arms 21 and 22 are formed on the shafts 18 and 20 respectively and are pivoted to a link 23 which is secured to a lever 24. The arms 21 and 22 are so positioned that as the lever 24 is swung it will rotate the shafts 18 and 76 20 in opposite directions, thus causing one of the cam sets 17 or 19 to operate while'the other is disengaged, and one set of fingers 11 or 13 will be engaging the seat back while the other is free.

The table 8 is reciprocated on the track 7 by a rack 25 secured thereto, which engages a pinion 26 on the shaft 27. The shaft 27 is rotated by a shaft 28 through the bevel gears 29 and 30. The shaft 28 is rotated through a belt 31 which travels over a pulley 32 on theshaft' and over a slidable clutch member 33. The slidable member 33 is adapted to engage either of the clutches 34 or 35 which are mounted on shafts 36 and 37 respectively, and said shafts are rotated in opposite directions through belts 38 and 39 respectively from a motor 40. Thus as the member 33 engages either of the members 34 or 35 it will be driven forward or reverse and the table 8 will consequently travel forward or backward. The member 33 is operated through a yoke 41 and lever 42. An

' extension 43 is formed on the lever 42 and 46 will strike the handle 44 and return the handle 42 to the neutral position. The converse is true in the return operation.

A plurality of cutting discs 47 are mounted in a frame 48, at the forward edge of the table 8'. The frame 48 is pivoted to a stand 49, and a counter-weight 50 keeps the frame raised above the table. A handle 51 is formed on the frame 48 whereby it is lowered to permit the discs 47 to sever the padding. The discs are rotated through a belt 52 which travels over pulleys 53 on said discs and over a pulley 54 which is again driven through any suitable source of power.

The operation of my machine is as follows: The seat to be padded is placed upon the table 8. The fingers 13 are clamped upon the seat by the lever 24. The padding which is formed in a continuous roll is threaded into the tubes 2. These tubes are now inserted into the pockets of the seat back by hand. The table is now moved forwardly and the tubes 2 are thus pushed into the pockets of the seat. The fingers 11 are now clamped upon the padding in the pockets 7 and the fingers 13 are released, after which the table is moved rearwardly which pulls the padding through the tubes 2 and removes said tubes from the pockets. The padding is now out by lowering the discs 47 and the seat may be removed from the table. In this particular machine, I have spaced the tubes 2 so that every other pocket in the set is filled at one operation. This leaves room for the fingers l3 and permits of the transverse contraction of the seat due to the expansion of the pockets by the padding.

Having described my invention, I claim:

1; A padding machine comprising a bed, a plurality of filling tubes mounted on said bed, a table reciprocally mounted on said bed and means at the forward and rear edges of said table adapted to alternately hold and release the work mounted thereon.

2. A padding machine comprising a bed, a pluralit of filling tubes mounted on said bed, a ta le reciprocally mounted on said bed, and means to hold either end of the work on said table.

3. A padding machine comprising a bed, a plurality of filling tubes mounted on said bed, a table reciprocally mounted on said bed, and a plurality of holding fingers adapted to alternately hold either end of the work on said table and pivoted to said table.
